Study Notes
Radial Artery
- Contains blood, red blood cells, white blood cells, platelets, and plasma
Intravenous Injections
- The median cubital vein is commonly used for intravenous injections due to its superficial location and ease of access
Triceps Brachii Muscle
- Extends the forearm at the elbow joint
Long Head Origin of Triceps Brachii Muscle
- Originates from the infraglenoid tubercle of the scapula
Posterior Compartment of the Arm Boundaries
- Bounded by the humerus laterally, the intermuscular septa medially and laterally, and the deep fascia of the arm
Bicipital Aponeurosis
- Provides support to the median cubital vein, making it easier to access during venipuncture
Circumflex Scapular Artery
- The suprascapular nerve is associated with the circumflex scapular artery
Terres Major, Triceps Brachii, and Humerus
- The quadrangular space is located between teres major superiorly, long head of triceps brachii medially, and humerus laterally
Blood Pressure Measurement and Pulsation
- The radial artery is commonly used to feel pulsations and take blood pressure
Triceps Brachii Muscle Action
- The triceps brachii muscle extends the forearm at the elbow joint
